Cold Spray for the Welding of Crack-Sensitive Alloys

Modifying 6xxx series aluminium alloys with the addition of 4xxx series fillers in foil or wire form can help reduce the susceptibility to cracking, however this can be difficult when working with complex assemblies with limited access. The cold spray technique provides a solution to this problem, coating all kinds of irregular and complex shapes with a buttering layer before welding. Find out how crack sensitivity can be reduced with the addition of a filler layer created with the cold spray process – as well as a comparison to conventional fillers:
